Hydroxypropyl methylcellulose
HydroxypropylMethylcellose (HPMC) noma i-hypromellosekuyinto esuselwas ye-methyl cellulose Ababusi. Ikonai-fibrous emhlophe noma emhlophe emhlophe noma emhlopheI-Cellulose Etheri-powder. Njengamanje i-cellulose Ababusi Ngokusebenza okuhle kakhulu emhlabeni, okuhlanganisa ukuqina, ukumisa, ukusabalalisa, ukuqinisa nokuqina. Hydroxypropyl methyl cellulose (HPMC) ayinobuthi, kulula ukuyisebenzisa, futhi kalula emanzini. Kuyi-polyanion kwisixazululo esinamanzi futhi inezindawo ezihlukile zomzimba. Ukusebenza okuthile Njengoba kuqhume:

Izici:
1. I-Solubinity: cishe i-infoluble ku-ethanol ephelele, i-ether kanye ne-acetone, futhi incibilika kusixazululo esicacile noma esincanyana se-colloidal emanzini abandayo. Ingachithwa kwezinye izixazululo ze-organic, futhi ingachithwa kwi-solvent exubile yama-solvents aphilayo.
2. Ukumelana nosawoti: kuzinzile ngezixazululo zamanzi lapho usawoti wensimbi noma ama-electrolyte akhona.
3. Umsebenzi ongaphezulu: ungasetshenziswa njenge-colloid evikela, emulsifier kanye ne-dispersant.
I-4. I-PH-STAYT: Inani le-PH lizinzile ku-3.0 ~ 11.0. I-viscosity yesisombululo esinamanzi ayithinteki nge-acid noma i-alkali.
